Lena Dunham

Why follow? Like her HBO comedy "Girls," her Twitter feed is funny, honest, revealing and unpredictable. It's also wonderful to witness how Dunham handles her critics without ever stooping to their level of disrespect.

Sample tweet "Approx. 78 people a day tweet me 'I've seen your boobs more than I've seen my own.' That CAN'T be true, says the literalist."

Be prepared for Recurring pictures of her dog and, of course, tweets promoting "Girls."
